B O N N E V I L L E P O W E R A D M I N I S T R A T I O N Residential LED Recessed Down light Fixtures RTF January 4, 2011

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N 2 Background  RTF deemed savings for specialty bulbs at April 2010 meeting.  LED Downlight measure was included:  Analysis was completed with same inputs and assumptions as reflector (specialty) bulbs

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N 3 Residential LED Down Light Fixtures  New LED recessed down light fixtures Recommend updating – Hours of use from 1.9 hours/day to ~3.0 hours/day  Specific hours of use by room type instead of average for applicable uses – Efficacy requirements – Increase to 50 Lumens/watt

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N 4 Updated Inputs – Hours of Use  RTF approved Hours of Use

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N RTF Hours of Use by Room Type Hours of Use (hours/day), by Room Type Room TypeDOE 2002KEMA 2005EMI 2007Average Dining room Kitchen Bathroom Living Room Exterior Bedroom Family/Den Hallway/Foyer /Stairs Garage Office 1.8 Basement/Utility Room Laundry Closet Other Average based on all room types

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N RTF Reflectors by Room Type  Analysis of reflectors  Not appropriate for downlight application  Likely only installed in dining room, kitchen, and living room Need to be dimmable 6 (from KEMA 2010, CA Statewide for CPUC) Locations of BulbsReflector Bathroom 9% Bedroom 6% Kitchen 21% Exterior 20% Living Room 9% Hallway/Foyer /Stairs 14% Dining room 3% Basement/Utility Room na Family/Den 7% Laundry na Other 2% Closet na Garage 1% Office 6% Total 98% Percentages by lamp type may not add to 100% due to rounding

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N Calculating Daily Hours of Use For lamp types not metered in CA study Use location* (room type) and hours of use by location** to determine lamp hours of use *The Cadmus Group, Inc. "Residential Retrofit High Impact Measure Evaluation Report", prepared for the California Public Utilities Commission, February 2010 **Navigant Consulting, "U.S. Lighting Market Characterization, Volume I: National Lighting Inventory and Energy Consumption Estimate Final Report", Table 5-9, p 40, Prepared for U.S. Department of Energy Office of Energy Efficiency and Renewable Energy, 2002 **KEMA, Inc.,”CFL Metering Study” for Pacific Gas & Electric Company, Southern California Edison Company, San Diego Gas & Electric Company, **Energy Market Innovations, Inc., "Puget Sound Area Residential Compact Fluorescent Lighting Market Saturation Study", November 2007

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N Updated Hours of Use Calculation  Reweight prevalence by applicable room types  3.35 hours weighted average Rounded to 3 for analysis

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N 9 Savings and Cost Effectiveness  3 hours  6 th Plan ProCost All other inputs consistent with approved analysis  Increase of about 20 kWh per bulb

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N 10 Proposal  Revise deemed savings for Approved LED Recessed Down Light fixtures for use in residential applications.  Recommended Measure Specifications: Must be Energy Star rated LED fixtures – 3 year minimum warranty In addition to Energy Star, product must also be rated at a minimum of 50 Lumens/watt.
